a std.experimental.allocator.RCIAllocator or std.experimental.allocator.RCISharedAllocator allocator object
Complexity: O(1)
auto sl = SList!int(theAllocator); auto csl = const SList!int(processAllocator); auto isl = immutable SList!int(processAllocator);
Constructs a qualified singly linked list that will use the provided allocator object. For immutable objects, a RCISharedAllocator must be supplied.
